Material Processing Examples Glass Glass is difficult to machine due to the brittleness and sensitivity to thermal stress. Due to very short pulse duration of femtosecond lasers, it’s possible to process glass in high precision and quality. This makes them well-suited for drilling, milling, scribing, and selective etching in fused silica, borosilicate, soda-lime, and sapphire substrates. The ultrashort pulse duration also allows formation of features such as high aspect ratio holes, microfluidic structures, and freeform geometries – finding applications in optics, semiconductor, and consumer...

Material Processing Examples Metal Femtosecond lasers enable high-precision processing of metals with minimal thermal impact, making them ideal for fabricating intricate microstructures, fine cuts, and surface modifications. Their ability to process a wide range of metals – including stainless steel, titanium, aluminum, and nitinol—supports applications from medical devices to microelectronics. In addition to cutting and drilling, femtosecond lasers allow for black/white marking and true color generation without chemical additives or surface contamination.

Material Processing Examples Polymer Polymers are widely used in various applications, including automotive, medicine, and consumer electronics. However, due to their inherent property of low heat conductivity, polymers are quite sensitive to heat. Femtosecond lasers, with their very short pulse durations, offer a solution to this problem by enabling the precise machining of polymers while preserving process quality.

Direct Refrigerant Cooling System Military-grade reliability The FemtoLux laser employs an innovative cooling system and sets new reliability standards among industrial femtosecond lasers. No additional bulky and heavy water chiller is needed. The chiller requires periodic maintenance - cooling system draining and rinsing and water and particle filter replacement. Moreover, water leakage can cause damage to the laser head and other equipment. Instead of using water for transferring heat from a laser head, the FemtoLux laser uses an innovative Direct Refrigerant Cooling method. The refrigerant...

Patent-Pending Method for Ultra-High Rate Bursts The Femtolux laser can operate in the single-pulse mode, MHz burst mode, GHz burst mode, and MHz + GHz burst mode. The burst formation technique based on the use of the AFL is a very versatile method as it allows to overcome many limitations encountered by other fiber- and/or solid-statebased techniques. Short GHz burst Fig 1. Measured 2.2 GHz intra-burst PRR burst of pulses containing a different number of pulses of equal amplitudes at 31.5 W average output power n=5 Long GHz burst Fig 2.

Pulse-on-Demand (PoD) Traditional laser triggering techniques struggle to maintain equally spaced pulses at high speeds (Fig.1, 2). Pulse-on-demand feature tackles this challenge and enables high-speed micromachining (Fig. 3). Time based laser triggering Fig 1. Complex shape scanned with time based laser triggering mode with a pulse repetition of 200 kHz and scanning speed of 6 m/s. The scanning started from the top right to the bottom right area. Overlapping pulses result in an overheated area. Position based laser triggering Fig 2. Complex shape scanned with position based laser triggering...
